CORPORATION. OF DELAWARE INSTRUMENT MOUNTING Application filed J une 25,

This invention relates to instrument mlpuntings for gages, thermometers and the li e.

The object of the invention is to provide an instrument mounting which will support the instrument in desired position and at the same time be adaptable to different instruments and to various situations met with in practice. 7

Other objects and advantages of my nvention will appear from the following description taken in connection with the accompanying drawing, in which Fig. 1 is a vertical sectlonal view of a mounting embodying the invention.

Fig. 2 is a horlzontal section on lines 22 of Fig. 1.

Fig. 3 is a vertical sectional view of a modified form of mounting, and

Fig. 4 is a side elevational view of a further form' of mounting with parts broken away to show the instrument beneath.

In the embodiment of the inventlon shown in the drawings an instrument A such as a thermometer is shown connected by a flexlble tubing 7 to a bulb 9. The mounting for the instrument comprises a disk or baclrplate 1 carried by a support 2 adjustably plvotally mounted on a collar member 3 by a screw bolt connection 4, the instrument A being removably secured to the disk 1 as by screws 0. The front face of the disk 1.is provided with a spool member j as shown adapted to have wound upon it any exoess length of the flexible tubing 7, this spool being provided with a slot 6 receiving the portion of the tube 7 as it issues from the back plate 11 of the in strument A after which the excess length of tubing is wound in a series of spiral turns.

- The tubing is then carried out through the rear opening 12 in the mounting to passon to the connection with the bulb.

- In the embodiment of the inventlon shown in Fig. 1 the temperatures of the bulb 9 are indicated on the instrument A, the 1n'strumen't being mounted adjacent the point of temperature to be measured, for lnstance, directly on a tank or other heated contalner 13 but spaced therefrom a desired dlstance. In such case a thin metal tube 14 of desired.

length is fitted to the bulb 9 to carry the lat-' ter and-passes up through the packing means 15 to have its upper end support the collar element 3 by means of a bushing insert 16 as shown, a slotted spacing tube 17 being provided receiving and enclosing the flexible tubing 7 and rigidly holding the bulb 9 at the bottom of the tubing 14. At the top of the bushing 16 is provided a flanged sleeve 18 A in convenient position to be read. The

supporting disk 1 is also adjustable around the axis of the tube 14 by loosening the set screw 19 and turning the collar member 3 on the bushing 16.

In Fig. 3 a shorter mounting is provided by I substitutinga shorter tube 14 for the longer tube 14 and with this shorter mounting the long slotted tube 17 is dispensed with and the bushmg 16 is fastened directly to thetube of the small spacer tube 10 protruding from the top of the bulb 9, the upper end of this tube 10 fittmg closely within the end sleeve 18 as shown.

In Fig. 4 the mounting is shown adapted to a placement of the instrument at a point distant from the bulb 9. The tubing 7 in such case is largely or entirely unwound from the spool 5 and carried out through the rear openlng 12 but not through the collar element 3, this collar being set in place upon a tilted to various angular positions aroun the axis of the bolt hinge 4 and may also be adtype to a rigid justed around the horizontal axis of the bracket 20.

The mounting of this invention not only supports the instrument in any convenient position with substantially universal adjustment but also houses the flexible connecting member and supports the bulb, at the same time providing a convenient attachment for any excess of the flexible tubing in protected and out of the way position. The mounting is readily variable to fit diflerent situations and is rugged and simple in construction and economical in cost of manufacture.

In Fig. 4 it will be seen that the instrument A may be mounted upon a fixed wall bracket 20, thereby permitting the bulb 9 to be carried by the operator to any location desired. During carrying of the bulb the same is kept in operative relation to the instrument A by the flexible tubing 7. Thus the temperature or other conditions to be registered may be obtained at several places while the instrument remains in a fixed position, it. being noted, however, that if desired the instrument may be inclined about the pivot 4 thereby possibly in some positions permitting the operator to read more easily the recorded pressure or temperature. On the other hand, it may be desired to make the bulb immovable with respect to the instrument and to accomplish this the operator would insert as shown in Fig. 3 the bulb 9 within a supporting tube 14, the inner end of the support 14 projecting through a suitable packing gland'15 into a suitable vessel, such as a boiler, vat or the like. The outer end of the tube would be connected to the bulb stem 10 as by the collar 16, upon which collar the instrument would be secured as by the bracket 3. The coil or tubing as shown in Fig. 4 will be wound upon the spool 7 by removing the back 1. Thus the bulb and instrument are supported in a relatively fixed position, the form shown in Fig.

. 3 being what might be termed a short form.

It happens sometimes that the customers do not know exactly what length of support 14 they may desire, and in order to permit the standard bulb to be used and held in spaced relation to supports of different lengths there is provideda sleeve 17 having a slot throughout its length. This sleeve and the supporting tubing 14 may be of indefinite length so that the purchaser after determining the distance it is desired to have the instrument disposed from the wall 13 may cut the sleeve. 17 and tubing 14 to the desired length. When this is done the sleeve 17 will first have the flexible tube 7 passed through the slot, after which the sleeve may be moved along the tubing and passed over the stem 10. The sleeve and bulb 9 may then be inserted within the tubing 14 and held thereinby the collar 16, which will be secured to the tubing 14 by a suitable screw, it being noted that the upper end of the spacing sleeve 17 rests within an annular recess of collar 16. By making the slot in the sleeve 17 it is unnecessary to pass said sleeve over the entire length of the flexconverted from a so-called long distance type into a so-called rigid stem type, a further ad vantage being that the bulb and supporting members are adapted for a number of diflerent installations.
